I wonder about the competition? The Karma dongle looks better, for what it's worth (https://yourkarma.com/), though it lacks the main feature of FreedomPop: it does not work internationally.

What about the competition - if you are not in the market for such a SIM at the very moment, but rather, looking for the long term evolution of this market? Here's a good one - Apple SIM: https://levels.io/roaming-is-stupid/

I agree with "levelsio", these 'mom and pap' small scale operations, which includes for me FreedomPop as well (who are they, really?) may not, probably will not change the world, maybe something large scale, like a global telecom company with the clout of Vodafone, T-Mobile, etc., or a big IT company like Apple/Google/Microsoft/Facebook, etc.
